I drop the bouncy ball on the hardwood floor. It makes a big thump and then bounces back up. I watch it hit the wall and bounce down again. I roll it with my foot and it zips away, bumping into the toy box. I kick it and it flies across the room to land in front of the couch. I pick it up and throw it high into the air. It goes up and then comes back down, landing on its side. I laugh and kick it again, making it skip along the floor like a little horse galloping.
